Power system state measuring and calculating method and device based on topological graph and electronic equipment

The invention discloses a power system state measuring and calculating method and device based on a topological graph and electronic equipment. The method comprises: acquiring the topological graph ofa power system; according to the power system topological graph, obtaining each node of the power system topological graph and at least one node adjacent to the node; constructing and calculating a gain matrix of each node according to each node and at least one adjacent node; according to the gain matrix of each node, calculating a system gain matrix of the topological graph of the power systemto obtain a state measurement result of the power system. The whole power system is divided into a plurality of nodes based on graph calculation, each node calculates the corresponding node gain matrix, and the state measurement result of the power system is calculated according to each node gain matrix, so that the state measurement result of the power system can be accurately and quickly calculated. 本发明公开了一种基于拓扑图的电力系统状态测
